ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

Webinar: MC&A and safety in advanced reactors in focus
Towell
Russell
Prasad
The American Nuclear Society’s Nuclear Nonproliferation Policy Division recently hosted a webinar on updating material control and accounting (MC&A) and security regulations for the evolving field of advanced reactors.
Moderator Shikha Prasad (CEO, Srijan LLC) was joined by two presenters, John Russell and Lester Towell, who looked at how regulations that were historically developed for traditional light water reactors will apply to the next generation of nuclear technology and what changes need to be made.

The 82.6 GHz/200 kW and 42 GHz/500 kW electron cyclotron resonance heating (ECRH) systems will be used in Tokamak SST-1 to carry out preionization and start-up experiments at 3.0- and 1.5-T operation. The 82.6-GHz gyrotron system has been tested for continuous waves (1000-s duration) using a conventional high-voltage power supply and for pulsed operation (200 kW for 1 s) using a regulated high-voltage power supply. The 42-GHz ECRH system is a pulsed system (500 ms), which will be used to carry out preionization and start-up experiments at 1.5 T (fundamental harmonic) on SST-1 and at 0.75 T (second harmonic) on Tokamak Aditya. The circular corrugated waveguide-based transmission line system contains two waveguide switches: one to test the gyrotron on a dummy load or the tokamak and the second switch to launch the ECRH power, either in SST-1 or in Aditya. The 42-GHz system has been tested on a dummy load, and the gyrotron delivers 500-kW power at beam voltage ∼49 kV and beam current ∼18 A. The output of the gyrotron is Gaussian (TEM00 mode) with mode purity >99%. The system is commissioned on both tokamaks (SST-1 and Aditya) to launch power in any tokamak.
